ttomey v Patented Dec. 21, 1937 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates generally to window structure, and particularly toan arrangement of a window frame in which a pair of vertically slidablesashes is mounted, the said sashes being in a certain position eachswingable on a vertical axis, and an important object of my invention isto provide a window structure of the character indicated which issimple, inexpensive, and which looks like an ordinary window structure.

Another important object of my invention is to provide a windowstructure of the character indicated above which enables the housewifeto easily and safely clean both the inside and the outside of the windowsashes, and which will en- 15; able eliminating a great part of thedanger and expense incident to the cleaning of windows in Otherimportant objects of my invention will be apparent from a reading of thefollowing de- 5, scription in connection with the drawings, wherein forpurposes of illustrationI have shown a preferred embodiment of myinvention.

Figure 12 is a perspective view of the upper part of the slide plate.

Referring in detail to the drawings the numera 5 refers generally to awindow structure in accordance with the present invention which includesthe window frame 6 which has the left hand side I and the right handside 8. Working in the window frame is the outer sash 9 and the innersash I I], which sashes, when horizontally aligned in a certain partlyopen position can be swung inwardly either singly or together to bringthe outer side of the sashes within the room in which the window is, sothat the outersides as well as the inner sides of the sashes may bewashed or otherwise treated without exposing the person within orleaning out of the window structure.

, Attached to the inner face of the window frame side I is the outerstop. II, the middle stop I2, and the inner stop I3. The facing edges ofthe stops are grooved as indicated by the numeral I4 to provideconfining channels for the slide plates l5 and I6 of the outer sash 9and the inner sash I0, respectively. The side edges of the slide platesI I5 and I6 are slidably confined in the grooves I4, and these slideplates are connected to respective sash strips I1 and I8 whose sideedges are slidably engaged with the facing edges of the correspondingstops I I, I2, and I3, as clearly shown in Figure 2.

The opposite edges of the sash work between sectional stops I9, 20, and2|.

The upper end of each slide plate has an inverted keyhole slot 22opening through the upper end thereof and this keyhole slot isregistered with a conforming opening 23 in the outer side of thecorresponding sash strip I8 to provide for reception of the lower endprovided with a knot or the like enlargement of the sash-cord 24 wherebyto connect the sash-cord operatively with the corresponding sash. Theslide plates extend the fullheight of the corresponding sashes and aresecured thereto by suitable means such as screws 25. The sash strips arepreferably of wood in a wooden sash construction, but when the windowstructure is formed'of metal or other suitable material, the entireconstruction including the sashes and the sash strips may likewise be ofmetal. v

The inner sash 9 has fastened at two or more vertically spaced points onthe left hand edge thereof a hinge leaf 26 which is of the same width asthe sash and is pivoted as indicated at 21 to a corresponding edge of acorrespondingly wide hinge leaf 28 which is fastened to the sash stripIT and has an anchoring indentation 29, clearly shown in Figure 2.Hinges 30 and 3| of the type just described are provided on the outer,

sash 9.

The inner sash I9 is provided with broadly similar hinges 32 and 33which are similarly fastened to the left hand edge of the inner sash l9and the corresponding sash strip l8 as shown in Figure 2. The hingestructures 32 and 33 are not of the same width as the sash l but arewider so that the pivot 34 is inwardly displaced from the inner side ofthe inner sash, so that when swung inwardly the inner sash will givesufficient of ordinary weather-stripping or felt, the present windowstructure is even more weather-proof and less liable to rattling duringstorms, than the ordinary window sash arrangements;

The right hand stops 20 and 2| are the sec-" tional stops and each iscomposed of an upper stationary section 36, a lower stationary section31, and a removable section 38, the fixed sections 36 and 31 beingfastened in any suitable manner to the inner face of the right handwindow frame 8.

The upper fixed sections 36 are outwardly and downwardly beveled asindicated at 39 and provided with a squared notch 40, these partsreceiving in abutment the angulated portions 4| and the squared tongues42 on the upper ends of the removable sections 38. a

The lower fixed section 31 is upwardly and inwardly beveled and providedwith the squared tongue 44 to abut the angulated portions 45 and thesquared notch 46 on the lower ends of the removable sections, so thatthe removable sections must be placed intoposition by first engaging thelower ends thereof with the described formations on the fixed section 31and then by an outward swinging movement engaging the formationsdescribed on the upper ends of the removable sections with thecorresponding formations of the upper fixed sections 36. V

The outer side of the upper partof each removable section carries aflush plate 41 which is secured by screws or the like 48 and has formedthereon the detent 49 which is provided with the horizontal working face59 which terminates at its inner end in a groove and the upwardly andinwardly angulated base 52 which terminates at its upper end in thegroove 5|. Each of the detents 49 is arranged to pass through an opening53 in, the window frame side 8 and also through an opening 54 in a latchplate 55. Below the opening 54 in each latch plate is a horizontallyspaced pair of ears 56 which support a horizontal pivot 51 on which arejournaled the lugs 58 on a J-shaped fiat spring'59 which has its upperend inwardly pointed through the opening 54 as shown in Figure 9 andagain in Figure 4. A spring 59'circumposed on the pivot 51 is arrangedto push the upper end of the spring 59 by the upper end of the saidspring, when the resiliency of the said spring assisted by the coiledspring 59 will cause a reverse movement on the part of the spring 59 sothat the upper end of the spring 59 will engage in the groove 5| with apositive action, so as to securely lock the movable section in place.Exerting a quick pull in the left hand direction will snap the detentout of holding engagement with the spring 59 and enable removal of thecorresponding removable section 38. The arrangements just describedapply equally to the sectional stops 20 and 2|.

When it is desired'to. clean the outer side of the sashes, the sashesare brought to such a position that their upper and lower edges comewithin the upper and lower ends of the removable sections 38. Thesections are then removed as indicated, whereupon the right hand edge ofthe sashes may be swung through the opening resulting from the removalof the sections to such inwardly swung positions as are indicated in'Figure 3. A simple reversal of the operations described will enablerestoring the sashes to their ordinary vertically slidable positions.

.Although I have shown and described herein a preferred'embodiment of myinvention, it is to be definitely understood that I do not desire tolimit the application of the invention thereto, and any change orchanges may be made in the materials and in the structure andarrangement of the parts, within the spirit of the invention and thescope of the subjoined claims.

.What is claimed is:

1. In combination, an ordinary window frame, three spaced stationarysash stops fastened to one side of saidframe and defining two sashreceiving channels therebetween, three oppositesash stops secured on theopposite side of said frame and defining twosash receiving channelsthere- 7 between, said opposite sash stops including an outer'stationarysash stop and two inner sectional sash stops, each sectional sash stopincluding upper and lower stationary sections and an intermediateremovable section, and two sashes slidably mounted channels defined bythe said opposite sash stops, the upper and lower ends of said removablesections being upwardly and inwardly inclined and dovetailed with thelower and upper ends respectively of the said upper and lower stationarysections, whereby said removable sections can be removed from thestationary sectionsonly by moving said removable sections inwardly andupwardly toward the opposite side of thewindowframe, said removablesections including detents extending laterally vtherefrom and throughopenings in the respecfastened to the said laterally inward face of saidsash strip, a second hinge leaf pivoted at its projecting outwardlytherefrom, said sealing element being arranged to be engaged andcompressed by a portion of said second hinge leaf into weather-sealingrelation between said sash strip and the sash when the sash is in closed5 position.
